As shown in the figure, the stay fixture 10 of the room mirror of the present invention includes an in-vehicle article 22 on one side and a mounting body 20 having a recess 24 that surrounds the outer periphery of the stay 3 of the room mirror 1 on the other side. The stay 3 is sandwiched and fitted into the recess 24, and includes a fixing portion 30 that fits according to the outer shape of the stay 3 or contacts the base 2 of the room mirror 1.
[0015] The mounting body 20 is a member that includes an in-vehicle article 22 on one side and a recess 24 that surrounds the outer periphery of the stay 3 of the room mirror 1 on the other side. The mounting body 20 shown in FIG. 1 is provided with the in-vehicle article 22 on the seat side of the vehicle and the recess 24 on the windshield side of the vehicle when attached to the room mirror 1. The in-vehicle article 22 shown in FIG. 1 is, as an example, a digital land meter, but it is not limited thereto, and various items mounted in the vehicle can be applied. The recess 24 is formed in a U-shape in plan view so as to surround a part of the outer periphery of the stay 3, and bolt holes 26 of the tightening bolt 40 are provided at a location where the fixing portion 30 described later fits to close the U-shaped recess 24. Further, the recess 24 is provided with notches 28 in both upper and lower main surfaces into which support pieces 32 of the fixing portion 30 described later fit.
[0016] The fixing part 30 is a component that fits into the recess 24 by sandwiching the stay 3 between it. The fixing part 30 is also a component formed to fit to the outer shape of the stay 3 or to contact the base 2 of the rearview mirror 1. The fixing part 30 shown in Figure 1-4 has a protrusion 32 that fits into a recess 5 provided on the back surface (vehicle windshield side) of the stay 3. The protrusion 32 is provided so as to protrude from one main surface of the main body of the fixing part 30. The fixing part 30 has support pieces 34 at both ends of the main body with the protrusion 32 as the center. The support pieces 34 are provided above and below so as to protrude from one main surface of the main body, similar to the protrusion 32. Furthermore, when the fixing part 30 is fitted into the recess 24, a bolt hole 36 is provided at a location opposite to the bolt hole 26, and is coaxial with the bolt hole 26. Such support pieces 34 are formed in four locations on the main body, top, bottom, left, and right, but the two lower support pieces 34 are provided with engaging pieces 38 (see Figure 2). The notches 28 that engage with the engaging pieces 38 have engaging holes 29 at opposite locations (see Figure 3), and when the fixing part 30 is fitted into the recessed part 24, the engaging pieces 38 fit into the engaging holes 29 and can be temporarily fixed. Note that the mounting position of the engaging pieces 38 is not limited to that shown in Figure 2, as long as it can engage and be temporarily fixed, it may be provided on the upper support piece 34, for example. The hand-tightened bolt 40 is a screw that can be tightened by hand without the use of tools. In this embodiment, a knurled screw is used as an example, but other types of screws such as wing bolts, knob bolts, and nylon screws can also be used.
[0017] The method for attaching the rearview mirror stay mounting bracket 10 of the present invention, as described above, will be explained below. The recessed portion 24 of the mounting body 20 is brought into contact with the stay 3 of the vehicle's rearview mirror 1 (see Figures 4(1) and (2)). The recessed portion 24 is larger than the cross-sectional diameter of the stay 3 and can be located at any suitable position on a part of the outer circumference of the stay 3. Next, the mounting body 20 is supported with one hand, and the fixing part 30 is held with the other hand, and the protrusion 32 of the fixing part 30 is fitted into the recess 5 of the stay 3. Then, with the fixing part 30 fitted onto the stay 3, the notch 28 of the mounting body 20 is fitted into the support piece 34 of the fixing part 30 (see Figure 4(3)). At this time, the engaging piece 38 of the support piece 34 fits into the engaging hole 29 of the notch 28, allowing the rearview mirror stay mounting bracket 10 to be temporarily fixed, and the optimal mounting position can be achieved in a single operation. The hand-tightened bolt 40 can be securely fixed by screwing it into the bolt holes 26 and 36 and tightening it by hand (see Figure 4(4)). With this rearview mirror stay mounting device of the present invention, the vehicle-mounted item to be attached to the rearview mirror stay can be positioned in the optimal position simply by fitting the mounting body 20 and the fixing part 30 together, and the vehicle-mounted item can be attached to the stay quickly and easily.
[0018] [Modification 1 (Cylinder)] Figure 5 is an exploded perspective view of the rearview mirror stay mounting bracket of Modified Example 1. Figure 6 is a cross-sectional view of the rearview mirror stay mounting bracket of Modified Example 1 when installed. In the rearview mirror stay mounting bracket 10A of Modified Example 1, the mounting body 20 has the same configuration as the mounting body shown in Figure 1, but the shape of the fixing part 30A is different. The fixing part 30A is shaped to fit the outer shape of the stay 3A, and is formed in a nearly semicircular shape in plan view, following the outer shape of the cylindrical member which is composed of two different diameters, large and small. The other components of the fixing part 30A are the same as those of the fixing part 30. In this modified example 1, the rearview mirror stay mounting bracket 10A can be positioned at the neck portion of the stay, or in other words, at the points of the two different diameters, by fitting the fixing part 30A along the outer shape of the stay 3A, which is a cylindrical member composed of two different diameters, large and small. After that, the same operation as in Figures 4(3) and (4) is performed. With this modified example 1 of the rearview mirror stay mounting device, the vehicle-mounted item to be attached to the rearview mirror stay (a cylindrical member composed of two different diameters, large and small) can be positioned in the optimal location simply by fitting the mounting body 20 and the fixing part 30A together, and the vehicle-mounted item can be attached to the stay quickly and easily.
[0019] [Modification 2 (square pyramid)] Figure 7 is an exploded perspective view of the rearview mirror stay mounting bracket of Modified Example 2. Figure 8 is a cross-sectional view of the rearview mirror stay mounting bracket of Modified Example 2 when installed. In Modified Example 2, the rearview mirror stay mounting bracket 10B has the same configuration as the mounting body 20 shown in Figure 1, but the shape of the fixing part 30B is different. The fixing portion 30B is shaped to fit the outer shape of the stay 3B, and is formed in a roughly U-shape in plan view along the outer shape of the rectangular prism member. The other components of the fixing portion 30B are the same as those of the fixing portion 30. The fixing portion 30B is formed to a length such that its upper end contacts the base 2 of the rearview mirror 1 when installed (see Figure 8). Furthermore, a cushioning material 50 is provided between the stay 3B and the fixing part 30B. The cushioning material 50 has a U-shape in plan view and is made of a material with a higher coefficient of friction than the stay 3B and the fixing part 30B. As an example, synthetic rubber can be used for such a cushioning material 50. In this modified example 2, the rearview mirror stay mounting bracket 10B can be positioned by fitting the fixing part 30A along the outer shape of the rectangular column member stay 3B with the cushioning material 50 in between, and by abutting the upper end against the base 1. After that, the same operation as in Figures 4(3) and (4) is performed. With this modified example 2 of the rearview mirror stay mounting device, the vehicle-mounted item to be attached to the rearview mirror stay (square column member) can be positioned in the optimal location simply by fitting the mounting body 20 and the fixing part 30B together, and the vehicle-mounted item can be attached to the stay quickly and easily. The shape of stay 3B may be a rectangular prism or a rod (cylinder).
